Do people really use this or any other of the cheatsheets you find online?

In my experience, any cheat sheet that I didn't make myself is useless to me. Going directly to the sheet without having done the synthesis of information yourself skips the most important part of the process.

Same for me. I need to start with the bulk of the info and start to compress it to be helpful to me.

Yes, you make your own sheets of the things you can never quite remember.

Often going through that process leaves you remembering them.

My first thought what an outstanding pdf, my second though; this should be in latex on github/gitlab, so people can contribute and maintain, I would love to add numerical psedo code to as much equations as I possibly can with my primitive comprehension of mathematics.

Let's do this; I just created https://github.com/Accacio/math-cheatsheet , When I get time I will implement CI/CD to genereate the pdfs

You may take a look on `.travis.yml`[0] used for MetaPost + ConTeXt rendition of Oliver Byrne's "The first six books of the Elements of Euclid".[1]

But thanks any way

What is this useful for, page 45? Rational Numbers: Every rational number can be written as r = [(r - 1) + (r + 1)] / 2 I would have expected p / q with p and q integers or some variation of this.

It's also totally trivial when you rewrite it slightly: (r + r + 1 - 1) / 2. So basically adding r to itself to get 2r then dividing by 2 gives you back r, with a pointless plus and minus 1 thrown in.

It's trivial only if you are simplifying mathematical expression.

When you have to go the opposite direction, you start with r and must turn it something that fits some other expression, there are infinite ways to proceed. Right ones rarely just pop up into your mind.

Remembering trivial identities things like that are useful as small intermediate steps when manipulating expressions.

That is "The Mathematics Handbook", v4.1
